I spent the weekend diving deep into Alexander Fuglesang’s story. A 5th-generation ocean entrepreneur who just cracked subsea desalination.

He’s crushing it in many ways:

→ Raised $9M Series A from top-tier VCs

→ 40-50% energy reduction vs traditional desal plants

→ 5th-generation CEO of Fuglesangs Group (est. 1855)

→ Deployed 70+ subsea pump systems through FSubsea heritage

→ Addressing UN projections of 40% water deficit by 2030

His breakthrough happens 500 meters underwater

While traditional desalination plants struggle with high energy costs, toxic brine discharge, and massive land requirements, Alexander’s team discovered something brilliant: the deep ocean does half the work for you.

At 400-600 meters depth, water is already pressurized through natural hydraulic pressure. Pre-filtration is minimal because the environment is clean and stable. There are no algae or biofouling issues, and zero brine toxicity problems.

It’s a completely different approach. Traditional plants use 95% more land, consume 40-50% more energy, and dump toxic concentrates into coastal waters.

Alexander spun Flocean off from FSubsea (his family’s 170-year maritime business) in 2024, taking decades of subsea expertise and applying it to humanity’s biggest challenge: water scarcity.

By 2030, global water demand will outstrip supply by 40%. Alexander’s not just building a company, he’s building the infrastructure for human survival.

Despite this breakthrough...

He’s making the same LinkedIn mistakes every deep-tech founder makes that could be costing him municipal contracts, Series B investors, and top engineering talent.

Let’s break down what he’s missing.

4 profile upgrades

1/ Headline buried his value prop.

Right now: “Founder and CEO of ocean technology companies in desalination and energy infrastructure space...”

Try: “Solving global water scarcity with subsea desalination | CEO @ Flocean | 40-50% less energy than land-based plants | 5th-gen ocean tech entrepreneur”

Lead with the problem you solve, not what you do.

2/ Banner shows nothing.

He’s got breakthrough subsea technology but a generic LinkedIn background.

Instead: Custom banner showing Flocean’s underwater systems with text like “By 2030, water demand will outstrip supply by 40%. Our subsea solution helps solve it.”

Show the urgency and the solution.

3/ About section is one sentence.

“Passionate about making a positive impact on the ecology and economics of the ocean space.”

This tells his ideal readers nothing. Where’s the 170-year family legacy? The $9M raise? The energy breakthrough?

Treat your About section like an elevator pitch for saving the world.

4/ Main CTA leads to the website’s homepage.

Websites are pretty brochures, not lead gen tools. A better use of this button would be their contact page, news Flocean was featured in, or at least the ‘how it works’ page since it’s a novel tech.

8 content upgrades

1/ Educate about the water crisis. 4.4 billion people lack access to safe water. Weekly posts with data, maps, and affected regions make the problem tangible.

2/ Share subsea engineering insights. “What I learned deploying pumps 3,000m underwater” is a good example of a post I’d love to read. His technology is so novel most people won’t believe it works until they see it.

3/ Document the family legacy angle. 5 generations of ocean innovation culminating in solving humanity’s water crisis? This story writes itself.

4/ Comment on water policy and climate reports. Investors want to see how founders think, not just what they build. React to California droughts, Middle East water politics, UN climate reports.

5/ Show customer proof points. Subsea desalination sounds like science fiction. Share case studies, installation footage, and municipal partnerships. Prove it’s real and scalable.

6/ Behind-the-scenes of subsea operations. Show Flocean technology being tested, team installations, and underwater footage. Water tech is inherently visual and dramatic, use that. “Here’s what it looks like 500 meters underwater” posts would go viral.

7/ Compare subsea vs land-based economics. Break down the real costs: “Why your city pays 2x more for water than it should.” Show energy consumption charts, land usage comparisons, and environmental impact data. Make the business case obvious.

8/ Connect with at least 50 target profiles per week. Water tech space is brimming with educators, innovators, and thought leaders. But you need to know where to find them. Make sure to proactively add them to your network.

Alexander’s sitting on one of the most important technologies of our time.

With the right content strategy, he could become the definitive voice for water security solutions.
